Introduction

This article will show you how to migrate a business integration solution containing an IBM® WebSphere® Business Integration Adapter for Enterprise JavaBeans (hereafter called a WebSphere EJB Adapter) into an Enterprise JavaBeans binding (hereafter called an EJB binding) in an IBM WebSphere Process Server environment.

The WebSphere EJB Adapter enables the integration broker to exchange business objects with enterprise beans that have been designed using the EJB architecture and deployed on an application server. Similarly, in a WebSphere Process Server environment, EJB bindings enable Service Component Architecture (SCA) components to invoke services provided by EJBs deployed on an application server.

Migration overview

In the existing environment, the WebSphere EJB Adapter receives a business object from the integration broker -- WebSphere InterChange Server. Using the information contained in the business object, the Adapter invokes the EJB deployed on a J2EE application server and returns the response back to the integration broker:

Migrating to EJB bindings has several advantages:

• EJB bindings support import and export bindings, while WebSphere EJB Adapter supports only request processing.
• EJB bindings support transactions, while WebSphere EJB Adapter does not.

Migration in IBM Integration Designer

Using the Migration Wizard in IBM Integration Designer, you can migrate WebSphere InterChange Server artifacts into deployable artifacts and place them in projects within an IBM Integration Designer workspace:

1. In IBM Integration Designer, open the Import Wizard and select File => Import. Under Business Integration, select WebSphere InterChange Server Repository and then click Next:

2. In the Import Wizard, browse and select the InterChange Server Repository project:
   
   Figure 4. Select WebSphere InterChange Server repository
   
   
   
3. In the IBM Integration Designer Library Name field, enter the name of a new designer library or select an existing one and then click Next.
4. The Configure Connector Migration screen lists the connector files in the InterChange Server repository. For the EJB Connector select EJB binding.
5. Click Add and browse to choose the EJB JAR file that is referenced by the InterChange Server repository. Click Next:

6. Choose the recommended options in the Select the Conversion Options screen and then click Next:

7. The Migration Summary page is displayed with the options chosen. If you need to change the entries, click Back, otherwise click Finish to close the wizard:

8. The migration is now completed, and the artifacts are generated and placed in different modules:

Testing

You can test the migrated application by implementing the output component in the EJBConnector project.

1. Deploy the generated modules in WebSphere Process Server and ensure that the required EJB service is deployed and running.
2. Test the flow by invoking the Test Component from the CustomerRetrieve module and sending the input request. Then you can invoke the service and examine the results:
